preg_match_all trouble

I can't seem to get what the regular expression would be to use preg_match_all.

It works to with ereg, but someone kindly pointed out to get all instances on a page I would need to use preg_match_all.

Can someone please steer me in the right direction with this? Here's the expression

preg_match_all ("[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}", 122.994.098.232122.222.098.232122.234.033.232, $out,PREG_PATTERN_ORDER);

Warning: Unknown modifier '{'
If I take out all the (1,3} I get:
Warning: Unknown modifier '.'

I know that it was valid with ereg. How come not with this? Any help would be greatly appreciated.

Hallo Robert,

try the following.

preg_match_all ("/[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}/", "122.994.098.232122.222.098.232122.234.033.232", $out,PREG_PATTERN_ORDER);

I will explain.

A regular expression needs beginning and ending delimiter /regexp/
I think you are searching for ip adresses and want to get numbers with points. But the point . used in a regexp stands for any symbol. So you must escape the the point /.
You should set your ip-adresses-String in quots because it is not a number. It is a string.

Hope you get it.
